Embodiment Construction

[0016] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.

[0017] Such as figure 1 Shown, the present invention proposes a kind of preparation method based on the polymetallic open-pit mine production operation plan of improved gray wolf algorithm, mainly comprises the following steps:

[0018] 1. According to the actual mining and transportation process of ore mining, with the goal of minimizing the mining and transportation costs of mining ore, an optimization model for the short-term production operation plan of open pit mines is established.

[0019] (1) The goal of minimizing mining and transportation costs

[0020] Usually, large open-pit mines have multiple ore outlets, and the types of ore mined at each outlet point will be different, and the mining costs of different types of ore will be different. In addition, the distance from each mining point to the crushing plant is different, and the co...

Abstract

The present invention is a polymetallic open-pit mine production operation plan preparation method based on the improved gray wolf algorithm. On the basis of the existing production operation plan, the allowable fluctuation range of the quality index of the selected ore is regarded as a constraint condition, and at the same time, the Based on the grade constraints of polymetallic components, a production operation planning model aimed at minimizing ore mining and transportation costs was established, and then the improved gray wolf algorithm was used to solve the model; compared with the original solution method, gray wolf The algorithm has the advantages of high solution accuracy and fast convergence speed, and is very suitable for solving complex function optimization problems under multi-constraint conditions. In the process of solving the optimization model of the polymetallic open-pit mine production operation plan, the operation plan that meets the actual production needs can be quickly obtained. The invention has important guiding significance for improving the utilization rate of mined ores, stabilizing the grade level of polymetallic open-pit mines, and improving the economic benefits of mining enterprises.

Description

technical field [0001] The invention belongs to the technical field of open-pit mine operation optimization, and at the same time belongs to the field of computer application and complex constraint function optimization technology, and in particular relates to a production operation planning method for polymetallic open-pit mines based on the improved gray wolf algorithm. Background technique [0002] Mineral resources occupy a very important position in my country's national economy. Continuously improving the economic benefits of mining enterprises and the utilization rate of mineral resources is the driving force for the continuous development of the mining industry. The preparation of production plan in open-pit mine plays a very important role in the process of mine operation. Open-pit mine production plan can be divided into short-term production operation plan and medium and long-term production plan. Generally speaking, the short-term production operation plan is to...
